There's a popular belief that switching between mineral oil and synthetic oil in your car's engine is a no-no. Some say it'll cause leaky seals and internal engine damage. So is it a myth or a reality?

By Kristen Hall-Geisler

It took researchers years to create quality synthetics that outperformed conventional oils, but there's little doubt that synthetics are now superior in most scenarios. What makes synthetic oil better?
